FARMER R. WILLIAMS, OF BELOIT, WISCONSIN, ASSIGNOR TO THE WILLIAMDEERING & COMPANY, OF CHICAGO, ILLINOIS.

MACHINE FOR MANUFACTURING TWINE FOR USE IN GRAIN-BINDING HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 429,829, dated June 10,1890.

Application filed September 18, 1889.

To all whom it may concern:

Be it known that I, FARMER R. WILLIAMS, a citizen of the United States,residing at Beloit, in the county of Rock and State of VViscousin, haveinvented certain new and useful Improvements in Machines forManufacturing Twine for Use in Grain-Binding Harvesters, of which thefollowing is a description, reference being had to the accompanyingdrawings.

This invention relates to a machine intended more particularly forproducing twine composed of a paper core and a fibrous covering woundthereon and twisted therewith, as described and claimed in myapplication for Letters Patent of the United States filed September 18,1889, Serial No. 324,332, designated Case G.

In the accompanying drawings, Figure 1 is a side elevation of mymechanism. Fig. 2 is a rear end elevation of the guide or former to actupon the paper. Fig. 3 is a cross-section of the twine produced by mymachine.

Referring to the drawings, A represents a rotary spinning-head having atubular journal, through which the twine is drawn, and by which it istwisted as in ordinary twine-forming machines. As the details of thismachine are familiar to those skilled in the art and foreign to thepresentinvention, it is deemed unnecessary to describe them furtherherein. They may be of any construction adapted for the twisting orspinning of twine.

B represents a toothed feeding-chain arranged to travel overasustaining-pulley b to deliver a sliver of fibrous material Gconstantly to an inclined guide F, over which it descends to be twistedinto the twine, as will be presently explained.

- D represents a long strip of paper coiled upon a supporting-drum d,from which it is delivered to the forming and twisting mechanism.

E is a stationary longitudinally-tapered former or guide, having incross-section a spiral or snail-wheel form, as shown in Fig. 2.

This former is located between the reel Serial No. 324,333. (No model.)

and the spinning-head. The paper strip is passed through this former andthence to the spinning-head, being first coiled or folded by the formerinto tubular shape, after which the tube is collapsed and twisted by thespinning 7 action.

The sliver used as a covering for the paper is delivered between theformer E and the spinning-head, and is thus wound spirally around thepaper, and also twisted or entwine 3. therewith, so that the two form.jointly a smooth, strong, and pliable .twine..

It is sometimes preferred to employ the fibrous coveringin a twistedcondition-that is, in the form of a cord,instead of in the form of asliver. \Vhen the cord is to be thus used, I provide a drum 0, on whichit is wound, and from which it may be led directly to the paper betweenthe former E and the spinning device.

The product of the machine is a twine having a fluted paper core and acovering of fibrous material, as shown in Fig. 3.

I do not claim herein the combination of the spinning mechanism and theformer, this combination being made the subject of 'a separateapplication for Letters Patent of the United States filed by me on the18th day of September, 1889, Serial No. 324,331, designated Case F.

Having thus described my invention, what I claim is 1. The combinationof a twisting or spinning mechanism, a former E, located in advance ofsaid mechanism and adapted to coil a paper strip into tubular form, andthe sup port arranged to deliver the fibrous covering between the formerand the spinning mechanism.

2. In combination with the spinning mechanism, the former E, the reel d,a guide F, and a sliver-feeding mechanism B.
